there are plenty of template files whare you could add the ad code.
for a more detailed suggestion, you need to define more clearly where you want to have your ads to show in your site.
where do you access source code/html?
Also, is it possible to paste the html code from adsense in a text-box widget? I can’t get that method to work.
I’m using the “twenty ten” theme
where do you access source code/html?
the source code is php with a html structure; how to edit it, see here:

Also, is it possible to paste the html code from adsense in a text-box widget?
yes, not a problem.
you might need to un-tick ‘Automatically add paragraphs’
I’m using the “twenty ten” theme
twenty ten will be overwritten with the next upgrade of your wordpress version – consider http://codex.wordpress.org/Child_Themes
there are plenty areas in twenty ten where you can add ads into the source code; however, the first step has to come from you – you need to clarify where you want the ads to show.
and don’t forget to search for a suitable adsense plugin.
I’ve had luck just pasting adsense code into text widget boxes, is there a reason you would have to use the adsense plugins?
there is never a reason to use any plugin if you can do the task without.
